I need some help, I took a sprite from the monster girl sprite sheet and made some edits to it for one of my pets. I made sure to check Do Not Write Color Space Information every time I exported a edited image, I'm trying to put it in the user folder.
This is not the first custom graphic I made for the user folder, and I edited my sprite sheet a bit and that works fine, but I'm wondering if there is a way to fix this without having to redo everything.
